TRACK AND WHEEL GAGE.

SPECIFICATION forming part of Letters Patent No. 556,790, dated March24, 1896.

Application filed August 5, 1895. Serial No. 558,306. (No model.)

To whom it may concern:

Be it known that we, THOMAS N. WARD, of Henderson, in the county ofHenderson, and MARTIN CRAHEN, of Princeton, in the county of Caldwell,State of Kentucky, have invented certain new and useful Improvements inTrack and lVheel Gages; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention contemplates certain new and useful improvements in trackand wheel gages, and the object is to provide simple and inexpensivemeans whereby different diameters of wheels and the width of tracks canbe quickly ascertained with accuracy. This we accomplish by providing arule, preferably of the folding pocket style, with a series of platescapable of being folded back. out of the way or extended beyond one sideedge at right angles thereto, said plates being located on said rule, soas to enable the operator to readily gage the diameters of a wheel andthe width of a track without the necessity of actual foot and inchmeasurement, the plates being set according to different standards.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawing, Figure 1 is a plan view of a folding ruleprovided with our improvements. Fig. 2 is a view of a portion of therule, showing the reverse side thereof; Fig. 3 is a detail. Fig. a is aView similar to Fig. 1, but enlarged.

Referring to the drawings, A designates a rule formed in sections aunited by hinges in such manner that they can be folded together so asto be convenientlycarried in the pocket. The rule is usually six feetlong, all the parts being extended. On one side, a, are scales ofgraduation.

B designates a series of plates attached to the other side, c3, of therule. Each plate is in the form of a hinge, having one member, I),rigidly attached to the side of the rule, and its other rncmbenb',capable of being extended outwardly at right angles to the longitudinalside edge of the rule, or folded back upon the member I), the hingeportion 6 being adja cent to said side edge. The hinged member Z) has astraight edge 5 and at the other side one of its corners is out off andbeveled, as at 13 to enable the operator to readily insert his fingerthereunder to turn said member outward. This cut-off also serves toaccommodate any flanged or projecting portion when two such plates arelocated near to each other. One of these plates is located at 0, withina short distance of one end of the rule, and it forms the gagc-pointfrom which all m casurcments are taken, the strr ight edge Z)" of eachplate serving as the measuring-point in each instance. Two gage-platesare located at D D, the former being set to indicate, in connection withthe plate at C, the least gage or diameter of inside of wheels, and thelatter, D, the greatest inside gage. Near these plates are located, at EE, two additional plates for indicating varying track-gages, while aplate at F, in connection with the plate at O,desiguates the extremediametrical wheel measurement. Thus it will be seen that the plates areset to different standards of measurement, and by means thereof thedifferent gages can be quickly ascertained. hen not being used, all orany of the plates can be turned back upon themselves and the sections ofthe rule folded together.

The advantages of our invention are apparent to those skilled in the artto which it appertains, and it will be specially observed that we haveprovided a simple and inexpensive track and wheel gage which will insureaccuracy of measurement and greatly facilitate ascertaining thedifferent gages of wheels and tracks.

Ve claim as our invention- 1. A track and wheel gage comprising a rule,or the like, having a series of sectional plates consisting each of arigid member, and a hinged member, said latter member having aninwardly-beveled corner, substantially as and for the purpose set forth.

:2. A track and wheel gage comprising a rule, or the like, having aplate, or the like, projecting therefrom at right angles to one of thelongitudinal edges of said rule, and a sespecification in the presenceof two subscribries of said plates arranged reiatively to said in'gwitnesses.
